4E-. -septic tank here shown (similar to type in California State Board of Health Special -Bulletin No. 8) is simple, easily construited and inexpensive. It has been used wiih remarkable success, confirmed by over five years' observation, in sandv. porous soil with a low water table and absence of hardpan rn upper strata.

. If soil is tight or poorly underdrained, or if the prob- lem of sewage disposal-is a complex one, we suggest writing the State Board of Healfh at Sacramentd"for special advice.

Attention is called to the simple but effective Redwood "V" trough outlet (see cross section).

Tables of value in determining sizes of tanks of vary- ing duties,_as well as_suggcstive layoutg for leaching systems, will be found in Bulletin No. -10, Californii State Board of Health.

Requisites For Good Sewage Disposal

(Froru Bulletin Na. 10, Calif ornia State Board of Health.)

"For resorts, homes and institutions, there is advised the use of a Septic Tank and a leaching system whereby the liquid leaving the septic tank may be absorbed by the soil itself without any occasion-for the sewage ever appearing upon the surface. From the time the sewage leaves the fixture in the house it should never be seen again. Obviously, the success of such a system hinges on how readily the particular soil will take up the sewage and how well the sewage has been prepared to be readily absorbed. The system requires Ior rts success:

"One-An available area of about .1 to .5 acre per 100 persons, depending upon the nature of the soil.

"l*g-A loamy, sandy, absorptive soil, preferabty with good drainage.

"Three-Absence of bedrock, hardpan and of ground water for a depth of at least 3 feet.

-"Four-A plumbing installation economical in the use ot u/ater.

"Five-Proper size and design of septic tank and leach- ing systegr.. These_ units cad not bC too large and the loosest soil in the vicinity should be sought."

New Type Roof Used at University

Douglas fir, {urnished by the Booth-Kelly Lumber Co', Eugene, Oregon, forms the wooden, trussless or Lamella roof, being placed on the new gymnasium at the University of Oregon by the Trussless Arch Roof Company of Los Angeles. Moreover, the Associated Students of the Unilr"riity who are building the gymnasium saved almost $13,000 by following the suggestion of Mr. A. C. Dixon, manager of Booth-Kelly Lumber Co., that they consider this type of roof.

Originated and used for many years in Europe, the Lamella or trussless roof was first introduced into California about two years ago. Two of them are already in use on the Hollywood Terminal Building and the Wilshire Arts Buitding, Los Angeles.

These roofs are built according to the patented "Lamella" system, consisting of a circular arch formed by a continuous network of wooded ribs called lamellas, connected.to r.."t.ty carry and transfer to the supports all arising ini"rn"f .tr.rr"r. Since no internal col-umns or supports of any kind are necessary, the Lamella roof gives- the maximum head room in gymnasiums, storage sheds, barns, studios, garages, ball rooms, etc.

The Booth-Kelly Lumber Company introduced the roof from California to Oregon, using it last spring-on-a store building. They were so pleased-with the result that 'tur' Dixon,"formerly a regent tt tn. Univer-sity, recommended it to the Associated students.After the archrtects, Las;;;" & Holford of Portland, had investigated the trussless roofs in use in Los Angeles, the plans for the gymnasrum were changed to permit the Lamella as an alternate \Mltn rt..i. Wn?n the Lids were opened, the price for the fabricated steel roof was $19,000 and for the Lamella or wooden roof, $6100.

Douglas Fir No. 1 common in Zxl2x.lO lengths^was ac.orai"ffy furnished by the Booth-Kelly, l'umber Company ior ln.- ioof of the new pavilion whictr is to be the largest svmnasium in the state ofOregon' It has a center span i6/1..1*iae and a length of. t62 f.eet. Specifications call i;; it i" be opened for Ise December 15' The seating capacity will be about 12,000.

Since this Lamella roof was completed, several fa-rmers i.t bt.eo" and California have specified it for, large barns' pru.iic?fry all fabrication for thiJtrussless roof can be done in the mili or shop, doing away with most of the usual high ori*a labor on the job. -The iumber necessary can be supolied from the regular cutting of any rvest coast salvmlll' F"i tttit reason, bluilders expect the Lamella roof to cqme into general use on the, Pacific Coast'
